[incubator/couchdb] Add a chart for Apache CouchDB (#2964)
* Add scaffolding for CouchDB chart * Move to a StatefulSet rather than a Deployment * Configure a headless service This configuration is necessary to ensure that the individual Pods have well-defined hostnames that are discoverable via DNS. * Make the minimal set of changes for a StatefulSet Lots of these changes need to be properly parameterized, but first let's get the basics working. * Fix the default variables for a 3 node cluster * Support generic Erlang VM flags as Values * Specify the location of sidecar image in values * Allow to override the podManagementPolicy * Ensure exact match between labels and selector * Simplify headless service definition The current version of the sidecar container expects the headless service to export SRV records for a _couchdb service, so there's no point in parameterizing the name here. In theory the port could be omitted, but there are a few unresolved issues with that configuration as of v1.7 so we just put in the stock CouchDB port number. * Do not pretend that we configure the CouchDB port In a future version we may be able to pass the port configuration to CouchDB using a ConfigMap, but for now the port on which the Pods are listening for HTTP requests is fixed. * Enable configuration of PVCs for the statefulset * Choose a more user-friendly name for spec.replicas Users familiar with CouchDB may wonder if "replicaCount" refers to the desired number of replicas per document, as opposed to the size of the cluster. * Clean up comments, improve example resource limit * Improve the Service / Ingress configuration This re-adds a traditional Service alongside the headless one so clients have a stable way to access the CouchDB cluster. It also refines some of the documentation around the Ingress resource. * Update the chart metadata * Add a basic README * Make some small doc changes to align w/ standards * Enable CouchDB configuration through ConfigMap * Configure admin account, cookie auth using Secrets * Tell the user to run finish_cluster after startup * Tweak the notes to use interactive password prompt * Fix the database-storage mount point * Automatically create admin account secrets This change enables the chart to be automically installed in a secure fashion with a single command. * Use GitHub username for maintainer name * Target latest StatefulSet API This also means we require Kube 1.8.

# CouchDB
|
||||
|
||||
Apache CouchDB is a database featuring seamless multi-master sync, that scales
|
||||
from big data to mobile, with an intuitive HTTP/JSON API and designed for
|
||||
reliability.
|
||||
|
||||
This chart deploys a CouchDB cluster as a StatefulSet. It creates a ClusterIP
|
||||
Service in front of the deployment for load balancing by default, but can also
|
||||
be configured to deploy other Service types or an Ingress controller. The
|
||||
default persistence mechanism is simply the ephemeral local filesystem, but
|
||||
production deployments should set `persistentVolume.enabled` to `true` to attach
|
||||
storage volumes to each Pod in the deployment.
|
||||
|
||||
## TL;DR
|
||||
|
||||
```bash
|
||||
$ helm install incubator/couchdb --set allowAdminParty=true
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.8+ with Beta APIs enabled
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
|
||||
$ helm install --name my-release incubator/couchdb
|
||||
```
|
||||
|
||||
This will create a Secret containing the admin credentials for the cluster.
|
||||
Those credentials can be retrieved as follows:
|
||||
|
||||
```bash
|
||||
$ kubectl get secret my-release-couchdb -o go-template='{{ .data.adminPassword }}' | base64 --decode
|
||||
```
|
||||
|
||||
If you prefer to configure the admin credentials directly you can create a
|
||||
secret containing `adminUsername`, `adminPassword` and `cookieAuthSecret` keys:
|
||||
|
||||
```bash
|
||||
$ kubectl create secret generic my-release-couchdb --from-literal=adminUsername=foo --from-literal=adminPassword=bar --from-literal=cookieAuthSecret=baz
|
||||
```
|
||||
|
||||
and then install the chart while overriding the `createAdminSecret` setting:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release --set createAdminSecret=false incubator/couchdb
|
||||
```
|
||||
|
||||
This Helm chart deploys CouchDB on the Kubernetes cluster in a default
|
||||
configuration. The [configuration](#configuration) section lists
|
||||
the parameters that can be configured during installation.
|
||||
|
||||
> **Tip**: List all releases using `helm list`
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release` deployment:
|
||||
|
||||
```bash
|
||||
$ helm delete my-release
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and
|
||||
deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the most commonly configured parameters of the
|
||||
CouchDB chart and their default values:
|
||||
|
||||

|
||||

| `allowAdminParty` | If enabled, start cluster without admin account | false (requires creating a Secret) |

| `createAdminSecret` | If enabled, create an admin account and cookie secret | true |

||||
| `erlangFlags` | Map of flags supplied to the underlying Erlang VM | name: couchdb, setcookie: monster
|
||||

|
||||

kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "couchdb.name" . }},release={{ .Release.Name }}"
